DUMP

-CART.

SPECIFICATION forming part of Letters Patent No. 398,562, dated February 26, 1889.

Application filed March 9, 1888.

To all whom it may concern:

BeitknownthatI,HARTWELLA.\VILKINs, of the city, county, and State of New York, have invented a new and Improved Dump- Cart, of which the following is a full, clear, and exact description.

The object of this invention is to provide a simple, cheap, and durable cart which may be quickly dumped, and which, when relieved of its load, may be readily returned to its normal position; and to this end the invention consists, essentially, of a cart-body rigidly mounted upon a cranked axle to which the shafts or thills are connected by hingejoints, the cart-body being held from accidental dumping by means of a tongue carried by a vertical crank-shaft, said tongue engaging a keeper that is secured to the cart-bod y, all as will be hereinafter more fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a rear view of my improved form of cart. Fig. 2 is a central longitudinal sectional view of the same, the cart-body, however, being represented as it appears when in its dumpingposition. Fig. 3 is a central longitudinal sectional view, the cart-body, however, being represent-ed in its normal position. Fig. 4 a perspective view representing the locking-tongue and its connections, and Fig. 5 is a partial plan view of the cart-body.

In constructing such a cart as the one illustrated in the drawings above referred to I provide a heavy cranked axle, 10, upon which there is mounted a bolster, 11, and to this bolster and axle the cart body or platform 12 is connected by clips or U-bolts 13, braces 14 being preferably arranged as shown best in Figs. 2 and b.

The tongues or thills u; are connected by the usual foot-board, 17, the connection between thefoot-board and the shafts orthills being stiffened and strengthened by braces 1 8,which are secured to the extending ends of the foot-board and to the shafts or thills. To the under side of the thills I connect coupling-irons 19, which irons are bolted to the thills and to a vertical board, 20, against which the thills abut, the

Serial No. 266,697. (No model.)

coupling-irons extending directly to the rear from. beneath the board 20, to be connected with the axle or the bolster carried thereby lower end of the shaft 21 there is secured a lockingtongue, 28, which, by turning the shaft 24:, may be brought into engagement with akceper, 30, that is secured to the forward end of the cart-body, the locking-tongue at this time passing through an aperture, 2, formed in the board 20.

The particular form of cart illustrated in the drawings is designed for the carting of cord-wood, and hence is represented with side rungs, it); but I desire it to be understood that an ordinary form of eartbody could be employed without departing from the spirit of my invention.

In operation the load is piled upon the platform or body 12, the tongue 28 at this time being in engagement with its keeper 30, and the cart having been drawn to the dumpingground, the driver, standing upon the board 17, throws the shaft 24-, by grasping its crank arm or handle 4:1, so as move the tongue 28 from engagement with its keeper, immediately after which the draft upon the shafts or thills will act to draw the axle 10 to the position in which it is shown in Fig. 2, and as the axle is so moved the cart-body will be tilted and its load discharged; but after the discharge of the load the weight of the driver, together with that of the crank-section of the axle and the forward section of the wagonbody, will act to return the wagon-body to the position in which it is shown in Fig. 3, immediately after which the driver throws the tongue 28 into engagement with its keeper.

In order that the load will tend to work for ward instead of backward, I mount the cartbody so that its floor or plat-form will incline downward from the rear end, and in order that the return of the cart-body to its normal position may be facilitated I so mount said body that the preponderance of the weight of the body will be in advance of the axle.

From the construction described it will be seen that an exceedingly cheap cart is produced, and that said cart will act rapidly and automatically to discharge its load.

Having thus fully described my inventioi'i, I claim as new and desire to secure by Letters Patent 1. In a dump -cart, the combination of a crank-axle, a body mounted thereon at one side of the center of its length, angular draftirons pivotally connected to the crank-axle, thills secured to the forward ends of the d raftirons, and a locking device for securing the body in its normal position, substantially as described.

2. In a dump-cart, the combination, with a crank-axle and a body secured thereto, of the thills provided with a foot board, angular draft-irons pivoted to the axle and having their forward ends secured to the thills, and a locking-tongue adapted to engage the body to lock it in position, substantially as described.

3. In a dump-cart, the combination, with a cra11kaxle and a body mounted thereon and provided with a keeper, of the thills 16, provided with the foot-board 17, the angular draft-irons 19, pivoted to the crank-axle and having their forward ends secured to the thills,

and the shaft 2%, provided with the lockingtong'ue 28 on its lower end for engaging the keeper of the body, snbstantiall y as described.

at. In a dump-cart, the combination, with a crank-axle and a body mounted thereon and provided with a keeper, of the thill-s 16, the footboard 17, the apertured board 20, the angular draft-iroi'is 19, pivoted to the axle and secured to the board 20 and to the thills, the thill-rungs 22, and the shaft 24-, journaled between the thill-rungs and provided with the locking-tongue 28, snbsti-mtially as herein shown and described.
